[CRASH] League of Legends.exe crashes after champ select. Can't Reconnect.

After joining PBE (but not using PBE client or account), myriad problems started occuring on my normal client and account. The most major is that whenever I try to join a match, I can get through champ select, but the game itself crashes instantly and returns me to the launcher, with a reconnect button. When I try to reconnect, the same thing happens again and again - the game crashes, it takes me back to the launcher.

I have tried on three different computers:

All options through Hextech Repair Tool Uninstalling and Reinstalling through the installer executable Resetting the all values to default in the in-game settings Rebooting Reinstalling my graphics driver on each computer Reinstalling all my input device drivers on each computer Reinstalling my network card drivers on each computer Running any combination of the league of legends executables in compatability mode for Windows 7 Starting a game on one computer and reconnecting from another Reinstalling the OS (Windows 10) from scratch on one of the computers, with League of Legends as the only app

I think I'm going CRAZY. Riot, please help. The logs are attached.

I'm on Patch 8.16 Windows 10 Build 17741.rs5_release 180814-1430
